F(-3)= 3(-3^2)
=3*9=27
therefore, g(f(-3))= 3-2(27)
3-54
=-51

Step-by-step explanation
RHS = cos 105° + cos 15°
= cos (90° + 15°) + cos (90° – 75°)
= – sin 15° + sin 75°
= sin 75° – sin 15°
= LHS
No x4+7 is not a solution but 4x+7 is if thats what you meant.
Assuming all of those numbers are meant to be multiplied together, we can rearrange 4 · 4 · 6 · 4 · 4 · 6 into the expression 4 · 4 · 4 · 4 · 6 · 6, which we can abbreviate with exponents as
